Application December 5, 1955, Serial No. 550,941

1 Claim. (Cl. 222-416) The present invention relates to improvements insiphons and its principal object is to provide a dispensing siphonarranged in such a manner that, after the first starting operation,desired amounts of liquid may subsequently be withdrawn at desiredintervals by the mere opening and closing of a valve.

My siphon is particularly intended for serving liquid over the counterfrom a relatively large receptacle or container disposed on the counter,the siphon allowing limited amounts to be withdrawn therethrough as thecustomers call for them and the siphon being so constructed that onestarting operation is sufficient to condition the apparatus forsubsequent dispensing operation.

A further object of the invention is to provide a siphon of thecharacter described that is sanitary in use and in which the point atwhich suction is applied is spaced from the point of discharge.

A still further object of the invention is to provide a siphon with avalve structure the fixed of which is formed integral with the siphontube, while the movable portion is mounted with freedom of limitedwithdrawal movement for cleaning and flushing operations, the withdrawalmovement being limited by a cushion member to guard against breakage,particularly where the siphon is made of glass or similar brittlematerial.

It is further proposed to arrange the suction means for starting theflow underneath the valve in such a manner that the closing of the valvebars the liquid from the suction tube, while on the other hand liquidsucked into the suction tube automatically discharges with the liquidfrom the main tube.

Further objects and advantages of my invention will appear as thespecification proceeds and the novel features of my invention will befully defined in the claim attached hereto.

The preferred form of my invention is illustrated in the accompanyingdrawing, in which Fig. 1 shows a side elevation of my siphon as appliedto a container disposed on an elevated platform,

Fig. 2 a fragmentary front view of a portion of the siphon, and

Fig. 3 an axial section through a valve used in my siphon.

While I have shown only the preferred form of my invention, I wish tohave it understood that various changes and modifications may be madewithin the scope of the claims attached hereto without departing fromthe spirit of the invention.

Referring to the drawing in detail, my siphon 1 is particularly intendedfor use in connection with a container 2 disposed on an elevatedplatform 3 which may represent the top plate of a counter over which theliquid is sold to customers in desired limited quantities.

The siphon tube is preferably made of glass or similar transparentmaterial and is bent in the conventional manner to present a goose neck4 and two legs 5 and 6 extending downwardly therefrom. The leg 5 ispreferably made of a length somewhat in excess of the height 2,774,522Patented Dec. 18, 1956 ice of the container and is mounted on a cork 7serving as a closure of the container. When positioned in its properplace the lower end of the leg 5 comes to a point within close proximityto the bottom of the container.

The leg 6 extends downwardly from the goose neck 4 in spaced relation tothe leg 5 and at an angle thereto so as to clear the outside of thecontainer. It is somewhat longer than the leg 5 and its lower endprojects below the top surface of the counter as shown.

The leg 6 is provided, preferably below the surface of the counter, witha valve 8 comprising a transverse bearing 9 formed integral with thesiphon tube and communicating with the passage thereof and a valve stem10 revolvable in the hearing. The bearing has a conical inner face, asshown at 11 and the valve stem has a similar outer face and has a groundfit with the bearing when in operative position with respect thereto. Inthe latter position the larger end of the valve stem projects somewhatbeyond the bearing as shown and is formed with a handle 12 by means ofwhich the valve stem may be turned.

The valve stem is formed with a transverse passage 13 adapted for liningup with the tube passage when the handle is turned into the properposition while the valve stem closes the tube passage when the handle isturned through a right angle.

The smaller end of the valve stem projects somewhat beyond the bearingand is formed, near its outer end and spaced from the bearing, with anannular groove 14 adapted to receive a cushioning ring 15, preferablymade of rubber. This ring allows of partial withdrawal of the valve stemin a lengthwise direction, but limits the withdrawal movement with acushioning effect. It may be readily removed, when it is desired towithdraw the valve stem altogether.

Below the valve I provide a suction tube 16 which communicates with thetube passage of leg 6 and is preferably formed integral therewith. Thesuction tube projects from the main tube at a right angle for a shortdistance, is then bent as at 17 to turn upward in substantially parallelrelation to the main tube to a point above the valve, and is then bentagain away from the main tube for convenience of access. The upper endof the suction tube is open, and when suction is applied to the upperend, with the valve in open position and with the bottom end of leg 6closed, liquid may be sucked from the container 2 into the leg 6 to thedepth of the valve or to any point desired.

In operation, the filled container is placed on the counter and thesiphon is applied in the manner shown. For starting the flow of liquid,the attendant opens the valve 8, closes the bottom end of leg 6, byapplying his finger or a cork, and applies suction to the upper end ofthe suction tube 16, which causes the liquid to rise in the leg 5 and todescend in the leg 6. When the liquid reaches the valve 8, the latter isclosed and the suction is discontinued. Now the apparatus is ready forany number of individual dispensing operations by the mere opening andclosing of the valve, until the liquid level in the container dropsbelow the bottom end of the leg 5.

If any foreign matter should lodge in the valve passage or around thevalve stem the attendant may readily flush the valve stem by pullingoutward on the handle. The rubber ring 15 limits and cushions thewithdrawal movement and guards against breakage, particularly if theassembly is made of glass. The valve stem may be readily removed forcleaning purposes upon removal of the rubber ring.

I claim:

A siphon of the character described, comprising a tube bent to present agooseneck and two legs projecting therefrom, one leg being longer thanthe other one and having a transverse bearing with a conical inner faceformed integral therewith so as to communicate with the leg passage, aconical valve stem revolvable in the bearing and having a ground fittherewith and having a transverse passage adapted for lining up with theleg passage when the valve stem is firmly seated in the bearing, ahandle at the larger end of the valve stem, the stem having an annulargroove in the other end spaced from the bearing, and a cushioning ringmounted in said groove and normally clearing the bearing to allow ofpartial withdrawal of the valve stem.
